450 FSE 2004 starting issues

[Yngvim]

I'm not shoure if it is running lean , wrong timing can cause the engine to run to hot, but you can try any voltage between 170mV and 290mV and find the sweet spot. The lower value is 4.5° opening on the throttle. It doesn't hurt to use injector cleaner.
Hope you will finde the setting you like

Just to be sure...every time when i adjust TPS, I should reset TPS also?!
Will try to play with the CO trim few days.
Still it's very strange that this stalling started in the middle of the ride....
